An encounter with leek that's squeakily undercooked can be quite offputting, and apart from soups, where the thinly sliced green flags add a characteristic whiff and bright colour, leeks are generally best kept away from water.

Fried leeks make a crisp, interesting garnish for bowls of Asian noodles or simple risottos. Cook them down slowly with butter and they swoon into a fondant state, while developing a savoury sweetness.

At which point, they can bring another layer of flavour and a gooey thickness to ingredients such as ham, cheese, potato and pasta, or served as a bed of puree under grilled sausages and fish. Why are leeks good for me? Botanically speaking, leeks are part of the vegetable genus Allium , which is part of the Amaryllidacea family. The edible section of the leek plant is a bundle of leaf sheaths, which is commonly confused with a stalk or stem.

While onions and garlic form a tight bulb, leeks produce a long cylinder of leaf sheaths that are blanched by spreading soil around them. The more of the plant that can be prevented from entering photosynthesis, the more nutritional punch it will have. These crunchy, firm veggies have a mild taste that is very similar to onions. Other common leek substitutes include green onions and shallots , both of which boast similar flavor profiles.

Native to the Mediterranean and Central Asia, leeks have also been a staple of many European diets for centuries, and they are found in many leeks recipes around the globe. The most widely researched feature of leeks is their ability to protect against different kinds of cancer, thanks to the presence of several cancer-fighting compounds.

One such cancer-protective component is inulin , a dietary fiber that belongs to the fructan family. Inulin stores energy in plants, usually taking the place of other carbohydrates, such as starch.

In one study published in Genetics and Molecular Research , inulin was tested for its ability to protect DNA from damage that causes mutations. Mutations from damaged DNA are often considered to be the reason many cancers form.

Other research has focused on the major impact of leeks on cancers of the gastrointestinal tract. Consuming Allium vegetables is also correlated with a significant decrease in risk for prostate cancer. Also referred to as DATS, this valuable substance has been shown to stop the growth of new tumor cells and prevent the formation of blood vessels in existing tumor cells. Leeks also contain allicin, an organosulfur compound that produces sulfenic acid as it digests. That may not sound thrilling, until you realize that sulfenic acid neutralizes the spread of cancer-causing free radicals in your body faster than any other nutrient.

Perhaps the most fascinating element in leeks, however, is kaempferol. This natural flavonol is an antioxidant , relieving oxidative stress in the body. For instance, the kaempferol in leeks is linked to a lower risk of chronic diseases, especially cancer. Test-tube research shows that kaempferol may fight cancer by reducing inflammation, killing cancer cells, and preventing these cells from spreading 11 , Leeks are also a good source of allicin, a sulfur compound thought to offer similar anticancer properties Animal studies reveal that ramps grown in selenium-enriched soil may help lower cancer rates in rats Similarly, high intake of alliums may be linked to a lower risk of colorectal cancer 29 , Leeks may improve your digestion.

These bacteria then produce short-chain fatty acids SCFAs , such as acetate, propionate, and butyrate. SCFAs can reduce inflammation and strengthen your gut health 32 , To prepare them, cut the roots and dark green ends off, keeping only the white and light green parts. Then, slice them lengthwise and rinse under running water, scrubbing away the dirt and sand that may have accumulated between their layers. Leeks can be eaten raw , but you can also poach, fry, roast, braise, boil, or pickle them.

They make a great addition to soups, dips, stews, taco fillings, salads, quiches, stir-fries, and potato dishes. You can also eat them on your own. Unlike cultivated leeks, wild ramps are incredibly pungent. Just a small amount of ramps can add a burst of strong, garlic-like flavor to your favorite dish. Leeks and wild ramps boast a variety of nutrients and beneficial compounds that may improve your digestion, promote weight loss , reduce inflammation, fight heart disease, and combat cancer.

These alliums, which are closely related to garlic and onions , make great additions to a healthy diet. These leek recipes will make you appreciate how delicious and nutritious the humble leek is. Onions are a staple in kitchens around the world and packed with nutrients and plant compounds with powerful health effects.
